BLOCK-DROPPING MECHANISM FOR BALING-PRESSES.

To all whom it may concern:

Be it known that I, LUTHER TRABUE, a cit-izen of the United States,residing at Girard, Illinois, have invented a certain new and usefulImprovement in Block-Dropping Mechanism for Ealing-Presses, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to baling presses, and particularly to theblock-dropping mechanisms used in baling presses for arranging t-hedivision blocks in operative position in the baling chamber.

One object of my invention is to provide a block-dropping mechanism thatcomprises means for automatically moving a blockholder into operativeIposition with relation to the baling chamber.

Another object is to provide a mechanism of the character describedwhich is Vso designed that the block does not have to be inserted in theblpck-holder at a certain period in the cycle of operations of theplunger or compressing member of the baling press.

.Another object is to provide a block-drop ping mechanism of thecharacter described which is so designed that the operator cannot inserta block in the block-holder when the mechanism which causes theblock-holder to be moved into delivering position is in operativeposition.

Another object is to provide a block-dropping mechanism which isso-sdesigned that a division block cannot be inserted in theblock-holder in such a manner that the block will become jammed duringthe operation of introducing it into the baling chamber. And stillanother object is to provide a block-dropping mechanism of novelconstruction which permits a division block to be inserted in theblock-holder from either side of the baling press.

Other objects and desirable features of my invention will be hereinafterpointed out.

Figure l is a side elevational view of a baling press provided with ablock-dropping mechanism constructed in accordance with my inventionshowing the block-holder arranged in receiving position and providedwith a divisionv block; Fig. 2 is a vertical longitudinal sectional viewsho-wing the block-holder in delivering position; Fig. 3 isSpecification of Letters Patent.

a similar view showing the plunger of the press retracted and thedivision block arranged in operative position in the baling chamber;Fig. 4 is a vertical sectional view taken on the line 4 4 of Fig. 2; andFig. 5 is a horizontal sectional view taken on the line 5-5 of Fig. 4.

Referring to the drawings whichillustrate the preferred fo-rm of myinvention,

il designates a plunger or compressing member of a baling press whichreciprocates in a baling chamber B, and C designates a hopper arrangedover the baling chamber so as to receive the hay or material which isforced into the baling chamber by the beater D. A block-holder E whichis arranged above the guideway in which the plunger A travels, formspart of the front wall of the hopper C, and at a certain period in thecycle of operations of the baling press said blockholder isautomatically moved from its receiving position, shown in Fig. l, intodelivering position, as shown in Fig. 2, so that the division blocktherein can drop downwardly into the baling chamber on the return strokeof the plunger A, as shown in Fig. 3. The block-holder E may be formedin various ways without departing from the spirit of my invention, butin the construction herein shown which illustrates the preferred form ofmy invention, the blockholder E consists of a substantially invertedchannel-shaped member open at both ends and provided with horizontallydisposed portions l which travelin guides or tracks 2 arranged adjacentthe upper edge of the passageway in which the plunger A travels, thehorizontal portions l of said blockholder being reinforced andstrengthened by means of brackets 3 connected to same and to the rearvertical wall of the blockholder.

. The means which automatically moves the.

block-holder from receiving position, shown in Fig. l, intodelivering-position, shown in Figs. 2 and 3, consists of devices 4 onthe plunger A which cooperate with devices 5 on the block-holder duringthe forward stroke of the plunger. I prefer to provide the plunger Awith a pair of upwardly projecting devices 4 arranged adjacent the rearend of same, and I also provide the block-holder E with a pair ofpivotally mounted devices or dogs 5 that are adapted to be moved intoand out of operative position with relation to the projections 4 on theplunger A, said dogs 5 being arranged adjacent the lower end of theblock-holder E between the horizontal portions 1 of said blk-holder.

The means herein shown for moving the dogsor pivotally mounted devices 5on the block-holder vinto and out of operative position with relation tothe projections 4 on the plunger, consists of a pair of pivotallymounted levers 6 which carry a. rod 7 that passes through 'elongatedslots 5"L in the dogs 5, and means, such, for example, as a rod 8,connected to one of said levers 7 for rocking them on their pivots so asto elevate the dogs 5 or move them into an inoperative position, asshown in broken lines in Fig. l, or move said dogs in the oppositedirection into operative position, as shown in full lines in Figs. 2 and3. VAny suitable means may be employed for locking the rod 8 so as tohold the dogs 5 in an inoperative position, the means herein shownconsisting of A a notch or recess 8a in the rod 8 that engages astationary member Sb when the rod is pulled forwardly, as shown inbroken lines in Fig. 1. The levers 7 are preferably made long enough sothat they will extend across the open ends of the block-holder E whenthe dogs 5 are in operative position and the block-holder is inreceiving position so as to prevent the operator from inserting adivision block in the block-holder at this time, namely, when themechanism which causes the block-holder to be shifted into itsdelivering position is operative or arranged in the path of travel ofthe projections 4 on the plunger.

The block-holder is provided with means for preventing a division blockfrom being positioned improperly in said holder or arranged in such aposition that it will become jammed during the operation of moving theholder into delivering position, the

stop member 9 may be mounted on the blockho-lder in any suitable manner,and any suitable device can be used for holding said stop member inoperative position. In the embodiment of my invention herein shown, thebar 9 is mounted in a bracket 1l connected to the outer vertical wall ofthe block-holder, and the spring 10, which exerts pressure on said bar,is connected to a supporting device 12 which is pivotally connected tothe bracket 1l in such a manner that the spring 10 can turn on avertical axis and thus permit one end of the stop bar 9 to yieldslightly during the operation of inserting a division b-lock in theblock-holder.

lhenever the operator desires to insert a block in t-he block-holder hemoves the rod 8 forwardly so as to move the lever G into an inoperativeposition with relation to the block-holder and also raise the dogs 5,and after the block has been inserted in the block-holder the rod 8 isreleased so that` the dogs 5 will move downwardly into the path of theprojections 4 on the plunger A. On the succeeding forward stroke of theplunger the projections 4 thereon engage the dogs 5 on the block-holderand thus automatically move the block-holder forwardly into deliveringposition, as shown in Fig. 2. As soon as the block moves off of thehorizontally disposed supporting member 13 on which it rested when theblock-holder was in receiving posit-ion, said block will drop downwardlyonto the plunger A, as shown in Fig. 2, and on the return stroke of saidplunger the division block will drop downwardly into operative posit-ionin t-hebaling chamber B, as shown in Fig. 3, as soon as t-he plunger Apasses from under said block. The block-holder and the stop device 9which coperates with same, are so constructed that the division blockcan be inserted in the holder from either side of the baling press, andas said stop device limits the lateral movement ofnthe division block itprevents it from being arranged in the holder improperly or in such aposition that it will jam against the side walls of the hopper D whenthe block-holder is moved into delivering position.

One advantage of a block-dropping mechanism of the constructionabove-de# scribed is that the operator does not have to watch the balingpress carefully so as to insert the division block at a certain periodin the operation of the plunger or move the block-holder manually intodelivering position for said mechanism is so designed that the block canbe inserted in the block-holder at any time when said holder is inreceiving position and left therein until it is desired to introduce theblock into the baling chamber, at which time the operator releases therod S so as to set the dogs 5 in operative position to be engaged by theprojections 4 on the plunger on the succeeding forward stroke of theplunger. Another advantage of such a block-dropping mechanism is thatthe division block cannot be inserted therein at a time when themechanism which causes the block-holder to be moved into deliveringposition is operative, this being due to the fact that the levers 6 areso proportioned that they extend across the open ends of. theblock-holder when the dogs 5 are in operative position. And stillanother desirable feature of my improved block-dropping mechanism isthat the blocks can be inserted in the holder from either side of thepress and Without liability of inserting them too far or arranging` themin such a position that they Will during the operation of introducingthem into the baling chamber. The outward pressure which the material inthe hopper C exerts on the block-holder tends to move said block-holderback to receiving position, but in case said blocloholder has not beenrestored completely to receiving position at the time it is desired tointroduce a block into same,

the operation of pulling the rod 8 forwardly to raise the dogs 5 causesthe block-liolder to be restored completely or moved clear back toreceiving position. The rod 8 is detachably connected to the lever 6 sothat said rod can be arranged on either side of the press, both sides ofwhich are provided With devices 8b Jfor locking the rod so as to holdthe dogs 5 in an inoperative position.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is:
